The MES-2/MES-3/MES-6 Complex and Regulation of Histone H3 Methylation in C. elegans

The C. elegans proteins MES-2 and MES-6, orthologs of the Polycomb group (PcG) chromatin repressors E(Z) and ESC, exist in a complex with their novel partner MES-3. The MES system participates in silencing the X chromosomes in the hermaphrodite germline. Loss of maternal MES function leads to germline degeneration and sterility. We report here that the MES complex is responsible for di- and tri...

Distinct regulation of histone H3 methylation at lysines 27 and 9 by CpG methylation in Arabidopsis.

Transcriptional activity and structure of chromatin are correlated with patterns of covalent DNA and histone modification. Previous studies have revealed that high levels of histone H3 dimethylation at lysine 9 (H3K9me2), characteristic of transcriptionally silent heterochromatin in Arabidopsis, require hypermethylation of DNA at CpG sites. Here, we report that CpG hypermethylation characterist...

Germline X chromosomes exhibit contrasting patterns of histone H3 methylation in Caenorhabditis elegans.

In mammals, one of the two somatic X chromosomes in the female is inactivated, thereby equalizing X chromosome-derived transcription in the two sexes, a process known as dosage compensation. In the germline, however, the situation is quite different. Both X chromosomes are transcriptionally active during female oogenesis, whereas the X and Y chromosomes are transcriptionally silent during male ...

Linker histone HIS-24 (H1.1) cytoplasmic retention promotes germ line development and influences histone H3 methylation in Caenorhabditis elegans.

RNA interference with one of the eight Caenorhabditis elegans linker histone genes triggers desilencing of a repetitive transgene and developmental defects in the hermaphrodite germ line. These characteristics are similar to the phenotype of the C. elegans Polycomb group genes mes-2, mes-3, mes-4, and mes-6 (M. A. Jedrusik and E. Schulze, Development 128:1069-1080, 2001; I. Korf, Y. Fan, and S....

Epigenetic Regulation of Histone H3 Serine 10 Phosphorylation Status by HCF-1 Proteins in C. elegans and Mammalian Cells

BACKGROUND The human herpes simplex virus (HSV) host cell factor HCF-1 is a transcriptional coregulator that associates with both histone methyl- and acetyltransferases, and a histone deacetylase and regulates cell proliferation and division. In HSV-infected cells, HCF-1 associates with the viral protein VP16 to promote formation of a multiprotein-DNA transcriptional activator complex. The abil...
